The method used by the team, described in a paper published in The Astronomical Journal, is reminiscent of the discovery of 301 exoplanets previously reported by Newsweek made using another algorithm, ExoMiner. All the exoplanets are within the Milky Way, our galaxy, meaning that the number of planets discovered in other galaxies remains just one. This list will be integrated into NASA's wider exoplanet catalog, which currently contains 4,575 worlds. Among the exoplanets discovered by the team, there are 57 planetary systems containing multiple worlds. This prompted the use of UCLA's Hoffman2 Cluster to process the data, which resulted in the compilation of a list of 366 new exoplanets and 381 other planets that had been previously identified. Zink's algorithm searched through the entire dataset collected by the K2 mission: more than 800 million images of stars, adding up to over 500 terabytes of data.Īlthough data from K2 has previously been used to understand how the locations of stars in galaxies influence what kind of planets can form around them, Kepler's software was not sophisticated enough to determine these planets' size or their location relative to their star.

"The catalog and planet detection algorithm that Jon and the Scaling K2 team devised is a major breakthrough in understanding the population of planets," Petigura said. Zink and Petigura, along with an international team of astronomers called the Scaling K2 project, then used the data to identify the exoplanets. This is something that astronomers must usually do with follow-up investigations and can be incredibly time-consuming. Zink's algorithm analyzes dips in light output from stars that could be caused by orbiting planets, eliminating the ones that are not caused by planetary signatures. The finding was made possible thanks to a planet detection algorithm designed by a UCLA postdoctoral scholar, Jon Zink, which searched through data collected by the NASA Kepler Space Telescope's K2 mission. "Discovering hundreds of new exoplanets is a significant accomplishment by itself, but what sets this work apart is how it will illuminate features of the exoplanet population as a whole," said Erik Petigura, an astronomy professor at the University of California Los Angeles. The find could enable researchers to understand better the evolution of planetary systems as well as showing them how unique, or not, our solar system is in the wider Milky Way. These extra-solar planets, or exoplanets, add to the catalog of more than 4,500 worlds discovered that orbit stars other than our sun. Astronomers have discovered 366 new worlds outside the solar system, including a star orbited by two gas giants that are in extremely close proximity to each other.
